Paper Abstract

This work presents, for the first time, research of new cavity topologies for mode-locked Er-doped fibre lasers. The proposed drop- and B-shaped cavities using dual-fibre optical collimator allow a relatively simple ring cavity with continuously adjustable length. Demonstrated is high-quality nonlinear-polarisation-evolution mode locking in an Erdoped fibre laser based on the new cavity configurations with pulses of several hundred femtosecond duration. Possibility smooth variation of pulse repetition rate allоws to stabilise this rate and apply femtosecond fibre lasers with proposed new cavity topologies in metrological and other fields where high stability of pulse repetition rate is required.
